2021 Mercedes-Benz B 1.3L Petrol · PL70 AEK

The vehicle maintains a roadworthy status, though the most recent inspection indicates a minor decline in mechanical perfection. During the test on 22 January 2026 at 19,437 miles, the tester flagged an offside rear service brake binding. While the report noted this was not yet excessive, it represents the first defect recorded in three years of testing, suggesting that the braking system is just beginning to require preventative attention. The mileage profile is exceptionally low for a five-year-old vehicle, averaging approximately 3,887 miles per year. Between January 2024 at 8,698 miles and January 2025 at 14,095 miles, the car covered 5,397 miles, followed by another 5,342 miles leading to the latest test. This consistent low-usage suggests light annual use, which typically reduces wear on drivetrain and suspension components. However, low mileage can sometimes lead to issues such as seized brake components or tyre-related deformation caused by long periods of standing. A buyer should specifically inspect the rear brake assembly personally to determine if the binding is caused by a sticking caliper piston or a corroded slider pin. Given the low mileage, it is also prudent to check the condition of the tyres for flat spots or perished rubber, which often affects vehicles that are driven infrequently. The clean records from the 2024 and 2025 tests indicate the structural integrity and primary mechanical systems were sound, but the recent brake advisory marks a shift from perfect maintenance to active monitoring to prevent future failure.
